Two Japanese Airlines Just Grounded Their Boeing 787s

Japan’s two major airlines, All Nippon Airways and Japan Airlines, voluntarily grounded their entire Boeing 787 fleets Wednesday after an ANA Dreamliner made an emergency landing because of a battery malfunction, Reuters reports. All Nippon Airways grounded all 17 of its Boeing 787 planes after a cockpit message indicating a battery problem forced one of its passenger jets to land at Takamatsu airport in Japan around 40 minutes after takeoff.

All Nippon Vice President Osamu Shinobe said at a press conference in Tokyo that the pilot detected a strange smell in the cockpit and cabin of the aircraft, according to Bloomberg.

All 129 passengers were safely evacuated from the plane via emergency slides and no one was hurt.

The “details of the problem were still being checked,” according to an ANA spokesperson.

Japanese authorities are investigating a fuel leak on a Japan Airlines Dreamliner at Boston’s Logan International Airport that occurred last Tuesday. A day earlier, a fire, also related to battery issue, broke out in the belly of a different Japan Airlines Dreamliner at the same airport.
